"On Collision W/ Ceiling" for Platform behavior

I want to reverse my platformer character's gravity when they make contact with a ceiling tile on the tilemap. There's conditions for checking floors and walls, but not ceilings.

How can I check if I'm colliding with a ceiling tile?

I'm aware I could put a second collision box on the ceiling and have that trigger it, but I'd rather have it work natively so I don't have to put extra collisions on every ceiling in the game.

You're right, putting invisible ceiling sprites everywhere is tedious!

I did it easier, I put a small invisible sprite on my character's head, which was a trigger for hitting the ceiling.

that's a very novel way to handle it, I'll test it out soon. thanks for the response :)
